AvantHiatus Posted February 10, 2015 Share Posted February 10, 2015 Compelling information about manipulation of temperature values. Chicago to Boston historic snows which means that's global warming and if they were having a snow drought it would be global warming. Good luck getting two back-to-back 3ft snowstorms pre-2000. However, it doesn't really prove or disprove anything. It's not like Canada is unusually cold. Boston can do well with what they would consider 'boot-leg' cold. Everything that now happens is spontaneously generated by AGW background conditions. The rest is just interaction and butterfly dynamics (chaos processes). Also, the enhanced winter regime is shifting north. In 09-10 it was from Saint Louis to DC. Link to comment Share on other sites More sharing options...

You are talking almost completely anecdotelly or just making up talking points. First off...Boston hasn't gotten "bootleg cold" during the pattern of big snowstorms...it's legit. Most of southern Canada and the eastern two thirds of the CONUS has been very cold the past 2-3 weeks. Secondly, the "enhanced winter regime shifting north since 2009-2010" is solely a function of Atlantic blocking...it was present in 2009-2010 and not present this year. Don't forget, many blamed the blocking on AGW...so now are you going to blame the lack of blocking on AGW too? That sounds like an interesting argument. The whole "AGW is always affecting our climate" argument is one of the worst red herrings in the attribution debate. The point of attribution studies is to determine the "net impact" of AGW...not that AGW is "always affecting the climate". Great, tell us how it is affecting the climate. For every storm AGW may cause to come closer or be snowier, there is a storm that it causes us to miss. So we want to know the net impact. Saying "AGW is always affecting the climate" means absolutely nothing scientifically in an attribution study. Link to comment Share on other sites More sharing options...
AvantHiatus Posted February 10, 2015 Share Posted February 10, 2015 It wasn't as thoroughly elaborated on as it could be but this is the banter thread. Talking points are for PR. It doesnt really matter it is what it is ORH. You know as well as I do that Eastern North America got stuck in the global cold pocket for two years in a row now. Granted this could be due to simple land-ocean contrast. I don't understand boot-leg cold being legit. It's boot-leg because it's moderated by AGW, yet Boston is still far enough north and on the east side of a continent to take advantage of ideal snow producing conditions. The proximity to the Gulf Stream also creates special dynamics in this region. Ironically, the GS has been running warm in-part to a two-pronged punch from the +AMO and GHG Forcing. Btw, if we ever get another long-term -NAO blocking fest you can kiss the Arctic goodbye. It's already torching moderately in a supposedly ideal setup.

It was the storm Chicago got like 20". One thing about "enhancement" from AGW. Too often I believe this is assumed that this always means worse for humanity. That is simply not the case. Yes, one-to-one simple cause and effect is the incorrect way to look at it, but as examples presenting it in this mindset, you could say the record long major hurricane landfall drought the CONUS has see since 2005 could be an "enhancement" from AGW. How about the record low U.S. tornado counts for the past three years? In the short term, we forget the first half of this winter in the NEUS was practically snowless. Yet for a solid year now, the mean trough position has been in the eastern U.S. It hasn't bee snowy the entire time in the two winters this has encompassed. Look at last Feb-March. All that cold, and we could not get anything for snowfall from a single storm like we have seen for New England in the last few weeks. A major issue that has nothing to do with the climate science itself but influences it is the human condition. We tend to assume the worst, especially when there is uncertainty involved. We rely on anecdotal evidence, confirmation bias, and "feel good" reasoning to come to conclusions and shape our perceptions. When things are bad in the here and now, we tend to ignore the overall picture on what has occurred over time (i.e. things are not so bad). All of this causes problems with the perception and context of climate change. Read this article. It has some good points. http://www.boston.com/news/weather/weather_wisdom/2015/02/the_great_snow_of_2015.html#comments Some excerpts: "There are so many ways to view all this snow. Meteorologcially it’s fascinating to see records being shattered. But the records only go back 130 years or so, a small amount of time when you widen the window of the past beyond what we’ve recorded. How do we know this type of event wasn’t occurring 500 years ago or some other time period? It’s historical to us, in our records, but where it fits in the big picture we really have no idea." "In 1987 when the stock market crashed it looked like a really big deal and in many ways it was. But nearly 28 years later that dip has been smoothed by time and is barely noticeable on a chart of the Dow Jones Industrial over the past 100 years. At some point in the future, maybe next week, maybe next year, all that is being missed during this Great Snow of 2015 will be barely a memory. You’ll likely remember the snowbanks, the shoveling, the days off from school, but most of the other stuff just fades with time." Link to comment Share on other sites More sharing options...
PhillipS Posted February 11, 2015 Share Posted February 11, 2015 There is a relevant post on ClimateCrocks today, which includes this excerpt from a Dr Michael Mann column in the Washington Post: You could treat this as ordinary weather, or, you could think about it in a climate context. Counter-intuitive though it may sound, the fact remains that — as I have noted previously — some kinds of winter precipitationcould indeed be more intense because we’re in a warming world. Consider, for instance, that sea surface temperatures off the coast of New England are flashing red, showing an extreme warm anomaly. That’s highly relevant — because warmer oceans have atmospheric consequences. “Sea surface temperatures off the coast of New England right now are at record levels, 11.5C (21F) warmer than normal in some locations,” says Penn State climate researcher Michael Mann. “There is [a] direct relationship between the surface warmth of the ocean and the amount of moisture in the air. What that means is that this storm will be feeding off these very warm seas, producing very large amounts of snow as spiraling winds of the storm squeeze that moisture out of the air, cool, it, and deposit it as snow inland.” Warmer oceans also increase the temperature contrasts that winter storms encounter when they hit the East Coast, notes Mann — and this ups their strength. “Heavy snows mean the temperature is just below freezing, any cooler and the amount would be a lot less,” adds Kevin Trenberth, a climate expert at the National Center for Atmospheric Research. “Warmer waters off the coast help elevate winter temperatures and contribute to the greater snow amounts. This is how global warming plays a role.” It is axiomatic that weather occurs under the climatic conditions of the moment - and AGW has changed some important climatic parameters including global temperatures, SSTs, and atmospheric water vapor. Because of AGW related changes to climatic conditions, every bit to today's weather, good or bad, mild or extreme, is influenced to some degree by AGW. So IMO the question of whether to attribute weather events to AGW should be reframed as: how much influence does AGW have on weather, and how is this influence projected to change as we continue to dump gigatons of GHGs into the Earth's atmosphere?

vortex95 Posted February 11, 2015 Share Posted February 11, 2015 Below is a table showing U.S. major hurricane landfalls for two time periods, each 43 years, 1926 to 2013.Total 1926-1969 Total 1970-201331 major hurr landfalls 19 major hurr landfallsby year, state landfall occurred and category is given. 1970 - TX31926 - LA3, FL4, FL3 1974 - LA31928 - FL4 1975 - FL31929 - FL3 1979 - AL31932 - TX4 1980 - TX31933 - TX3, FL3 1983 - TX31935 - FL5 1985 - AL3, NC31938 - NY3 1989 - SC41941 - TX3 1992 - FL51942 - TX3 1995 - FL31944 - FL3 1996 - NC31945 - TX3, FL4 1999 - TX31947 - FL4 2004 - FL4, FL3, FL31948 - FL3 2005 - LA3, LA3, FL31949 - FL3 1950 - FL3, FL31954 - RI3, MA31955 - NC31957 - TX41959 - SC31960 - FL41961 - TX41964 - LA31965 - FL31967 - TX31969 - MS5it was much more severe meteorologically prior to 1970. For example, look at FL 1944-1950 when major hits were spread out over successive years...that's worse than a cluster of hits in a short time (i.e. 2004-2005). Why?, there had been more time to rebuild, and then some of the same areas got damaged or destroyed all over again, not to mention yearly repeated evacuations. FL got hit by 15 major hurricanes 1926-1969, and only 7 from 1970-2013. And there is New England...1938, 1944, 1954 (2), and 1960. That averages one hurricane every 4-5 years over that 22 year period. How many hurricanes have made landfall over Long Island or the New England coast in the subsequent 52 years since 1960?, three...Belle (1976), Gloria (1985), and Bob (1991) and none of these were as strong as any of the ones 1960 and before. Also, look at the longer gaps between major hits 1970-2013 compared to earlier.I realize the U.S. is only one small part of the globe, but we are the among the richest countries with huge coastlinedevelopment, and all the focus is on us it seems. This of course means nothing as to what the atmosphere ends updoing, but the prevailing mindset seems to be when it affects us, it is the the proverbial end of the world.The 150 year record has shown the Atlantic Ocean has the most variable tropical basin in the world over time. So canwe expect more severe times to return eventually?, I think so, regardless of what the climate does or doesn't do.We often hear about the "new normal". Well, if recent years are the "new normal", I am really afraid of the "old normal"as far as U.S. hurricane landfalls are concerned. Link to comment Share on other sites More sharing options...

The zone for TC's may shift a bit north in a warmer world, but the storms themselves don't become any more frequent (in fact, probably less frequent) and the intensity is shown to be a negligble change on the order of 1-4%.

Being well-balanced and skeptical you should not be as quick to dismiss anything based on 30 years of data, if that. My current understanding is that some natural oscillation is counter-acting the AGW signal, at least in the Atlantic basin.

That said, I'm not overly confident. I'm just telling you what the literature says. The literature certainly has changed in the past and will in the future. Whether TCs are included on that list of changes remains to be seen. But thus far the observations generally match the modeling for AGW and TCs (unlike some other model-related studies)...the models say generally no change in TC frequency or intensity, and the observations support that. Could it change? Sure. But saying it will is complete conjecture and not currently supported by the literature. Link to comment Share on other sites More sharing options...
